The Energy Monitoring PICtail™ Plus Daughter Board is a power monitor circuit that uses the highly integrated PIC18F87J72 single chip energy meter IC. This low-cost design does not use any transformers and requires few external components. It includes both an isolated USB connection for meter calibration and access to the device power calculation, and an isolated PICtail Plus connection for Explo…

The PIC18F87J72 Single-Phase Energy Meter Reference Design is a fully functional single-phase meter based on the highly integrated PIC18F87J72 single-chip energy meter IC. This low-cost design does not use any transformers and requires few external components. The PIC18F87J72 directly drives the LCD, and includes both an isolated USB connection and a non-isolated RS-232 interface for meter calibr…

The MCP3901 and PIC18F65J90 Energy Meter Reference Design is a fully functional IEC Class 0.5 compliant single-phase meter. This low-cost design does not use any transformers and requires few external components. The PIC18F65J90 directly drives the LCD, and includes both an isolated USB connection for meter calibration and access to the device power calculations.

The CRD5463PM demonstrates the CS5463 power measurement IC. It has an integrated AC-DC power supply, voltage and current sensors, and isolated UART/USB interface. Working with the GUI software, it provides accurate real-time measurements of line voltage, load current, line frequency, active power, reactive power, apparent power, power factor, and temperature.

This metering module can be used to build a Class 0.5 Single-phase standalone or microprocessor based meter with or without tamper detection for power line systems of V = 140 to 300Vrms, Inom / Imax = 2/20ARMS, F = 45 to 65Hz and Tamb = -40 to +85°C.
